the "data and estimation" folder contains the data, JAGS model files, and R scripts used to generate the results reported in the paper. The R scripts in this folder merge the data, estimate the models, and produce model output. The "graphs" folder contains R scripts that will produce the figures in the paper. You must create output files (with .rda suffix) using the R scripts in the "data and estimation" folder before running the R scripts to create the figures. Some of the models will take a long time to run (maybe more than a day) and the output files will be large.
